Why Choose Navien?

With Navien’s unique and proprietary heat exchanger design the NPE-S is able to achieve the industry leading 0.99EF / 0.97 UEF.

Navien’s unique condensing heat exchanger design uses heat from the flue gases to preheat the water in the most efficient way available today. This design requires less input to achieve a higher output than a comparable tankless water heater. That means savings on gas and a better performance. For example, a NPE-210S with an input of 180,000 BTU/H has a higher output (~178,000) than a non-condensing 199,000 BTU/H unit with an output of ~163,000.

With Navien’s condensing technology, you get the best of both worlds: the best value and “ultra condensing efficiency”, which offers substantial savings and contributes to a green-friendly environment. Plus, the installation and venting processes are easy, cost effective, and Navien’s products are simply the best in quality and performance.

We’re tired of running out of hot water, high energy bills and constantly heating a big old water storage tank. That’s why our contractor recommended Navien. They’re the best in the industry, with the highest efficiency, according to Energy Star. Now we get endless hot water when we need it and we’re not heating water when we don’t.”
